5. Eliminate drafts. 6. See “Venting”. Failure to Ignite 1. Main gas off. 2. Defective gas valve. 1. Open all manual gas valves. 2. Replace gas valve. Condensation of Water Vapor 1. Improper venting. 1. See “Venting”. Burner won’t turn off 1. Defective or sticking automatic valve. 2. Excessive gas pressure (The supply gas pressure must not exceed 1/2 psi or 14” w.c. 1. Replace valve. 2. To correct this situation contact the utilitysupplying the gas. Incorrect Gas Input 1. Gas input not checked. 2. Clogged orifice. 1. Re-check gas input. 2. Check orifice for clogging. If clogged, clean out the hole carefully with a smooth wood toothpick. (Do not in any way enlarge or distort it). Not enough heat 1. Appliance undersized. 2. Incorrect supply pressure. 1. This is especially true when a dwelling or room is enlarged. Have the heat loss calculated and compare to the appliance output (approx. 70% of input). Your gas company or installer can supply you with this information. If appliance is undersized, replace with correct size unit. 2. Check supply pressure as outlined above. Too much heat 1. Combination control valve sticks open. 1. Replace combination control valve. TROUBLE SHOOTING CHART - PILOT AND VALVE Burner won’t turn on 1. Gas valve not turned on. 2. No voltage to valve. 3. Defective thermostat. 4. No 115 Volt Line Voltage. 5. Auxiliary limit switch open. 6. Blocked flue switch open. 7. Gas valve defective. 1. Turn gas valve to “on” position”. 2. Check for 24 Volts to Valve. 3. Check wall thermostat. 4. Jump fan switch to check for voltage (fan will come on). 5. Push on red buton to close. 6. Push red button in to close. 7. Replace gas valve Page 18 TROUBLE SHOOTING CHART - PILOT AND VALVE - CONTINUED SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION Pilot won’t light, or stay lit (STANDING PILOT) 1. Air in line. 2. Defective thermocouple. 3. Pilot flame too low. 4. Manual reset switch not engaged. 1. Bleed line. 2. Replace thermocouple. 3. Adjust pilot flame. 4. Push on button. Pilot won’t light, or stay lit (I.I.D. PILOT) 1. Sparker won’t work. 2. Sparker won’t light pilot. 3. Manual reset switch not engaged. 1. Check wire connections. 2.a. Pilot flame too lean. 2.b. Turn valve to “on” position. 2.c. Check for pilot restriction. 3. Push on button. THE FOLLOWING IS A LIST OF POSSIBLE CAUSES AND CORRECTIVE ACTIONS FOR BLOCKED FLUE SWITCH PROBLEMS POSSIBLE CAUSES CORRECTIVE ACTION 1. Blockage in vent pipe 2. Burner is overfiring 3. Improper vent system. A) Vent too short B) Restriction in ventsystem caused by offsets C) Incorrect vent pipe4. Incorrect header plate location. 5. Vent pipe not down on the header plate securely6. Loose connections on the vent safety wiring harness 1. A) Check vent pipe for blockage, such as bird nest, wasp nest, twigs, leaves, etc. 1. B) Check inside the bottom of the vent pipe to make sure the top of the draft diverter did not rip the inner liner causing it to block part of the vent opening. 1. C) Check that no insulation from the header plate got caught on top of the draft diverter when the heater was inserted into the wall. 1. D) Check that the vent cap is properly installed, not shoved too far down on the vent pipe. 2. A) Check the manifold pressure. 2. B) Check the rate, NOTE: This appliance was orificed for elevations up to 2,000 feet. When installed at higher elevations refer to orifice chart in “Controls” section of instructions for proper orifice size. 3. Correct vent system. A) The vent should terminate a minimum of 12 feet above the floor. See Figure 1. Also, the top of the vent must be at least 2 foot above any obstacle within a 10 foot radius, including the roof. See Figure A on Page 4. B) All type “B” vents shall extend in a generally vertical direction with offsets not exceeding 45 degrees, except that a vent system having not more than one 60degree offset may be allowed. Any angle greater than 45 degrees from the vertical is considered horizontal. The total horizontal run of a vent plus the horizontal vent connector shall be not greater than 75 percent of the vertical height of the vent. C) Use listed BW type vent pipe. Do not use transite or any other type of ceramic pipe for venting. Do not use single wall pipe. When venting into a masonry chimney the chimney must be properly lined and sized for this gas furnace. The use of type B or a flexible chimney liner is recommended. 4. Consult Figure 6 for correct header plate height. 5. You must use a base plate (obtained from the vent pipe manufacturer) on top of the header plate, or wall furnace. This will lock the vent pipe down and prevent the draft diverter from shoving it up. 6. Check the connections on both the switch and the gas valve. Tighten if necessary. DO NOT BYPASS THE BLOCKED FLUE SWITCH: TO DO SO COULD EXPOSE THE CONSUMER TO PROPERTY DAMAGE, PERSONAL INJURY OR POSSIBLE DEATH.
